ELECTRIC-SIGN SOCKET.

Specification of Letters Patent.

' PatentedSept. 5, 1916.

Application filed June 11, 1914. Serial No. 844,518.

To all'cuhom it may concern:

Be it known that we, LoUIs FELDMAN, a subject of the King of Rouma'nia, and MAX DAVIS, a subject of the Emperor of Austria- Hungary, and residents of the city and county of Denver, Colorado, have invented I certain new and useful Improvements in Electric-Sign Sockets; and we do declare the following to be a full, clear, and exact description of our invention, such as will enable others skilled in the art to which it .appertains to make and use same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in electric light sockets, especially designed for use in connection with electric sign boards,

and has for its primary object the facilitation of placing the sockets in position on the sign board.

Another object and advantage of the invention is the fact of the provision in sock- -ets of said character constructed so as to have a solid mechanical connection to the board Without the use of bolts or screws.

Still another object of the invention resides in the provision of a socket of the character set forth constructed to be selfadjusting to an thickness of sign board. In the use 0 our invention, many other objects and advantages embodied in the construction thereof will readily appear, and we wish it understood that all such objects and advantages are anticipated and within the scope of our invention.

We will now proceed to describe our invention with reference to the accompanying drawing forming a part hereof.

In this drawing, Figure 1 is a side elevation of our improved socket in position on the board; Fig. 2 is a side elevation partially in section, showing the position of the socket before it has been fully turned into place on the board Fig. 3 is a plan view of the rearward side of the socket; Fig. 4 is a cross sectional view through the socket on the line 4-4 in Fig. 3; Fig. 5 is a plan view of the opening punched in the sign face for the reception of the socket;

. and 18.

Fig 6 is a side elevation view partially in section showing a modified form of the socket; 1n Figs. 1, 2 and 6'the face or metal part of the signboard is shown insection.

Corresponding and like arts are referred to in the following speci cation and indicated in all the views of the accompanying drawing by the same reference characters.

Let the numeral 5 designate an electric light socketformed of the usual insulating material. This socket is provided with a flange or rim 6, adapted to engage one side of the sign board 7, said flange forming a facing for the said socket and concealing the opening 8 formed in the sign board for the reception of the said socket. This flange 6 serves to prevent the passage of the socket through the sign board, andcooperates with spring clips 8 and 9, arranged on opposite sides of the socket as shown in Fig. 5. These spring clips are held in position on the un* der or rearward side of the flange 6 by means of bolts or screws 10. The outer ends or heads of the screws 10 are sunk below the surface of the flange 6 in the depressions 11.

The opposite or threaded ends of bolts 10.

secure the spring clips in the depressions 12 and 13, and extend rearwardly as shown at 14 and form a stop for the backward turning of the socket, when it is placed in position on the sign" board.

The socket properis formed of asingle piece of insulating material, which is provided with the usual recess 16 havin usual metal lining 15, provided with hreads which cooperate with similar threads formed on a light bulb. This metal lining is held in positionin the recess 16 by the bolts 17 The bolt 17 passes through the rearward part of the socket and secures the current carrying strip 19, the opposite current carrying strip 20 is secured to the socket by means of the bolt 21 which passes through the rear of the socket and connects with the center contact thereof 22. ,These current carrying strips 19 and 20 respectively terminate in the clamp or wire holders 22 and 23, the two pieces forming the current carrying strip are each bent in semicircular shape at their outer extremities,

forming a circular opening into which the wire is snapped and soldered in place.

The opening 8' in the sign base is provided with the four square off-sets 25 equally spaced around its outer edge.

, In operation the socket is placed in the opening 8 and revolved in the direction of 'the arrow 24, Fig. 3, until the spring clips 8 and 9 engage with the square off-sets 25 at which time the clips and the sign face will be turned downwardly as shown in Fig. 2, until the projecting screws 14 engage in the square off-sets 25. It will not be possible to revolve the socket in the sign face in any direction, and the elastic tendency of the spring clips 8 and 9 will hold the socket tightly against the said sign face regardless of the thickness thereof.

In Fig. 5 there are four off-sets 25 shown. Of course only two of these are used by the socket, but we employ the four so that the socket may be set in either of two directions.

In .Fig. 6 is shown a form of the socket employing different spring clips. These spring clips 26 and 27 are secured to the rim or flange of the socket in a manner similar to the first described clips, and pass downwardly along the side of the socket in a recess provided therefor as shown at 28. The lower extremities of the clips are bent up wardly and inwardly as shown at 29.

In operation this socket is simply pressed into the recess of the sign face, the clips 26 and 27 will spring inward until the socket is fully in position at which time they will spring outward as shown in Fig. 6 and prevent the removal of the socket. With this socket we employ only a simple round hole in the sign face. I

While we have described and illustrated herein a specific form of our invention, it is understood that the same may be modified without departing from the spirit of our invention, or the scope of the appended claims.

Having thus described our invention, what we claim and desire to secure by Letters Patent is extended at an angle in the direction of thecircumference of said receptacle, said light receptacle being rotarily adjustable to fixedly engage the latter with said supporting member, the free extremity of said spring adapted to pass through said aperture during the adjustment of said vreoeptacle and engage said supporting member on the opposite side from said flange.

The combination of a support-ing member with a light receptacle, said supporting member having a light receptacle opening therein, the light receptacle having a flange on one side thereof adapted to engage with said supporting member, and a spring having one extremity secured to said light receptacle and extended from its securing point at an angle in a. direction circumferential of the said light receptacle, said light receptacle being rotarily adjustable to fixedly engage the latter with said supporting member, a portion of said spring adapted to pass through 'said light receptacle opening and engage said supporting member on the opposite side thereof from said flange.

3. The combination of a supporting member with a light receptacle, said supporting member having a light receptacle opening therein, said opening having an offset extension thereof, the light receptacle having means thereon adapted to engage with one side of said supporting member, a spring, and a fastening member engaging one extremity of said spring with said light receptacle and having a portion extended beyond said spring parallel with the longitudinal axis of said light receptacle, said spring extending from said fastening member at an angle to the longitudinal axis of said light receptacle, said light receptacle being rotarily adjustable to fixedly engage the latter with said supporting member, said spring adapted to enter said aperture and engage the said supporting member on the opposite side thereof from said means, said extended portion of said fastening member adapted to engage with said supporting member to prevent reverse rotation of said light receptacle.

4. The combination of a supporting member with a light receptacle, said supporting member having a' light receptacle opening therein, the light receptacle having a member on one side thereof adapted to engage with said supporting member, and a fastening member having one extremity secured to said light receptacle and extended from its securing point at an angle to the longitudinal axis of said light receptacle, said light receptacle being rotarily adjustable on its longitudinal axis to fixedly engage the latter with said supporting member, said fastening member adapted to enter said light receptacle opening and engage said supporting member on the opposite side thereof from said engaging member of the light receptacle.

5. The combination of a supporting member with a light receptacle, said supporting member having a light receptacle opening therein, the light receptacle having a flange on one side thereof adapted to engage with said supporting member, and a spring having one extremity secured to said fiangeand having its other extremity free, the free extremity of said spring adapted to enter said opening and engage the said supporting member on the opposite side from said flange.

In testimony whereof we afiix our signatures in the presence of two witnesses.
